How to Install Solar Panels Battery Banks for Solar Energy

Now we come to our battery bank for our Solar system. This one is made up of six volt cells combined in different ways to get the voltage we need for our individual inverters. We're going to be using the big Zantrax 1,000 watt this time, so we'll need two six volt cells, in series, to come up with that twelve volts. If you take your battery and connect a positive to a negative terminal that leaves you with a positive and negative terminal and you can get your twelve volts here. If you connect four batteries in series, positive to negative,.

You come up with twentyfour volts. And if you needed a fortyeight volt system, which is not uncommon, you'd simply expand and use more batteries. But for a twelve volt system we'll just use two. And, they're really the most dangerous part of the system. If you look down inside there, you can see a liquid and that liquid is sulfuric acid and will really seriously burn you and that's why we have a base here, Baking Soda, and if you get that acid in your eyes or in your clothing you can neutralize it with this. So, very.

Important to have this for safety. We can get a look at some of that acid here with the hydrometer, this is what you measure the actual specific gravity of the acid inside. And you can see we have several of these disks floating. We have about three disks floating with one at the bottom. So we know that this two batteries, or at least this battery, is about seventyfive percent charged. So, we're going to be very careful with that acid and stick this back here in our little cup. It's also important to note that the gases that.

Can Your Entire House Run On Batteries

Wouldn't it be weird if one day in the future you were buying a home and the listing said, batteries not included Yeah well, that could totally happen. Hey there people, Julian here for DNews. Electricity is pretty great. It powers my toaster, my fridge, my hairdryer, my clothes dryer, my air conditioner, my humidifier, my dehumidifier, and my pc I use to watch science tutorials. I think I'm gonna keep using it. The problem is, everyone in all the other houses feels the same way, usually at about the same times.

Of day, and they're driving the cost of those tasty kilowatts up in the evening. Of course during the day if you don't want to use power from the grid, you could get some solar panels and harvest sunlight, but that's not helpful when the sun's down, also known as nighttime, also known as the time I need to have electricity to turn lights on to not bang my shins on all the furniture. Enter the battery powered home. The idea is a rechargeable battery stores energy from solar panels during the day or from offpeak hours when grid energy is cheapest, and uses.

That energy during the rest of the day. The problem is if you've ever bought batteries you know they cost approximately one arm andor one leg. Elon Musk thought that was a silly hangup for what is otherwise a great idea and decided to do something about it. Elon Musk, for y'all that don't know, is basically what would happen if Tony Stark lost the goatee. His interests range from online money movement to commercial space flight to, most importantly for this topic, electric cars. His company Tesla Motors has been refining electric car batteries for years, engineering them to be lighter, longer lasting,.

And more efficient. Why don't we take all those batteries, and put them on a wall So they did that. The Tesla Power wall Is basically a bunch of lithium ion cells in a sleek case. They're compartmentalized and liquid cooled to solve the knotty problem of overheating and burning your house down, something that is generally undesirable. If you wanted it as your main power supply there's a model that can store and discharge up to 7 kWh daily and costs $3000. Best of all it should last 10 years, which is approximately.

8 years longer than my laptop battery made it before it wouldn't hold a charge anymore. The trick to this longevity is how much power it outputs. It's only pumping out 2 kW continuously and peak output is 3.3 kW. The problem that then arises is some appliances will use more than that output. An electric clothes dryer could draw that much power on its own. So if you want dry clothes, I hope you weren't planning on using a microwave too. If you wanted to be not reliant on the grid at all, you'd probably need a few powerwalls.

To go with your solar roof panels. Depending on where you live, your power consumption can vary widely, but the average US home in 2011 used 940 kWh per month. A solar setup of that size would cost over $11,000, not including installation or taking tax credits into account. Then you'd need 5 Powerwalls to store all of that sunshine juice, so that's another 15 grand. It's an expensive prospect right now, but as the cost of batteries and solar panels continue to drop, individual homes that are independently powered could.

Become a great way to kick our fossil fuel habit. Inexpensive home batteries are looking like a promising innovation. They're not the only company innovating. Intel creates the breakthrough technologies that make amazing experiences possible. Having Intel inside makes for better experiences outside. Intel drives innovation with products like processors, wearables and IOT devices, and within data centers. In the PC and beyond. Going green sounds like a lot of effort. Is it really worth it Trace explains why yes, totally, it is, right here. Would you use the powerwall Would it be a supplement for your energy use or would you.

FYI Four Main Types of Solar Systems

Hi, and welcome to FYI , a new informational tutorial series from Wholesale Solar. My name is Josh Roelofs and today we're going to talk about the different types of solar systems available. The first and most common option for a PV system is a gridtied power system in which the solar panels and your inverter is tied into the household electrical system and it simply offsets your energy usage. A gridtied system offers the lowest overall system cost, fastest return on investment. It saves money on energy expense by sending energy back into the grid and turning your.

Meter backwards. It's ideally suited for people who are trying to save money on energy costs. The drawback to a gridtied system is that it does not offer protection from power outages. When the power goes out, your gridtied system is going to shut down. So if you're in an area where the power is unreliable, or you want to protect against power outages, you'll want to consider one of our other options. A gridtied with battery backup system is going to offer the best and most comprehensive features for most people. It can provide backup power to your appliances during a power outage.

It can also turn back your meter to offset energy costs. This system is especially suitable for people who live in an area where the power is unreliable or people with critical equipment like computers, or a pump, or something you need to run during a power outage. Like coffee. Gridtied with battery backup is going to offer a combination between cost savings and independence from the power grid. An offgrid system is completely independent from the power grid. It's especially great for areas where there's no grid power available, or where it's incredibly expensive to bring.

In the power grid. You can literally buy land anywhere and install your own power system. This offers the highest level of independence for people who are seeking selfsufficiency. However, there's a price for that independence. The batteries are going to wear out quicker because they're being cycled every day. Typically they'll be replaced every 510 years, depending on the system. BUT. did I mention total independence A gridassist system works similar to and uses the same equipment as an offgrid system. Solar panels recharge your batteries and your appliances run off the battery system.

The difference is A gridassisted system can use the power grid as a backup power source. The grid will turn on automatically when the batteries are low, because it's nighttime, or because there's not enough solar power to support your appliances. This will save you some money on your energy bill, especially if you're in an area where they charge higher rates during the day based on TimeofUse Metering. These are your 4 main system options available from Wholesale Solar. If you have questions or need more information, feel free to check out our website or give.

Elon Musk Tesla and SolarCity Will Accelerate the Development of an Energy Solution

The reason I put so much time and effort into creating Tesla was because, it's always said to me that the transportation won't go electric and should go electric, but we have an unpriced externality in the negative effects of gasoline and on the environment and also in the wars that we fight and national security and that kind of thing. Whenever you have an unpriced externality you can't quite rely on the market to do the right thing. So in order to have electric vehicles come sooner than they otherwise would.

Electric vehicles were always going to be the longterm transportation mechanism, but to make that day come sooner, you have to bridge the gap with innovation. That was the goal with Tesla is to try to serve as a catalyst to accelerate the day, the day of electric vehicles. And I think when all is said and done, I am hopeful that historians will look back on Tesla and say that Tesla advanced that by at least 10 years, which that would be a huge victory of mine. in my mind.

SolarCity, of course, is on the energy production side of things because it doesn't help if we have sustainable consumption of energy, but then that energy isn't produced in a sustainable way. I feel quite strongly that solar power will be the single largest source of electricity generation by midpoint of the century. In fact, just a simple extrapolation of the growth of solar power would for sure, that that's obviously going to be the case. And also when you consider that the earth is almost entirely solar powered today and that the fact that.

We're not a frozen ice ball at say 4 degrees kelvin and it's just due to the sun. And the whole ecosystem is powered by the sun. There's just an itty bitty amount of energy that we need to do complicated human things. It's a tiny amount of energy really compared to what the sun puts on the earth every day. And we just need to capture a little bit of that and turn it into electricity. So we have to try to accelerate that with innovation. And that's what SolarCity is about.

How to Install Solar Panels Wiring Fuses to Solar Panel DC Side

Alright, now we're ready to wire up our fuses and charge controller on the solar panel DC side. We've got our charge controller ready to go, we're just going to slip our BX wire, which I've actually insulated one of the tips, here, so we don't spark our machine. We'll feed that wire through a strainer leaf and put another little strainer leafer, here, on our BX. Tighten that up a bit. So you can see with that little spark there, that we do have power and we should use some.

Kind of fusing in here just so, if something goes wrong and the fuse blows out instead of the electronics. So, we've got a standard car fuse, this one's rated 40 amps at 32 volts. Really, all we need is about a 15 amp fuse, here, but this should give us some measure of protection. We're going to wire this through on the positive side. We've got a fuse holder that matches our fuse, and we'll just strip off a little bit of this insulation here. We'll form a little edge, a crimp, on this so it will loop under our device nicely. Got.

Screw terminals, here, and we're just going to slip that positive wire right under one of our terminals. In a larger installation this will be done in a separate box, but for a small one, this should be fine. Now, we need to run the other side of the positive wire to our charge controller and we need a little piece of wire for that. So now we've got our little jumper wire ready to go, we're going to strip that off and connect it to the other side of our fuse. Demo So.

Burning Stuff With 2000F Solar Power!!

In a previous project I found a free tv and turned it into a giant solar scorcher. This shoots out a deadly beam of sunlight, that's hot enough to abuse food, melt metal and burn things you probably shouldn't. Today seemed like a good day to play with my Solar Scorcher. I positioned my frame and found the focal point, then added some concrete tiles as a base for my projects. Ok, I've got power, and I'll test it out with this piece of wood and when the light makes contact.

I've got instant fire. The sunlight at this spot is around 2000 degrees Fahrenheit, enough to melt this spot of concrete into a glowing orange liquid. I'm curious to see what I can do with all this heat so I've filled a glass bottle with water and I'll punch a hole in the cap. It's incredible to see that the instant I focus my lens on the bottle, it starts smoking. Just a few moments later this water is so hot it's boiling, and I'm a little nervous the bottle might blow. Yep, there it goes. The glass pieces are melting and that's cool,.

But now I want to try this on some food. I'll get some hot dogs, and when they hit the beam they really do get hot. This might be a little well done for my taste, and I'm still hungry so let's try an egg. The egg is actually working very well. It's so reflective it doesn't burn as fast, and even my wife is interested. A little salt and pepper and it's tempting to try a bite. Ok, so I wasn't actually expecting to eat this, but it looks safe enough, and.

Even my kids are anxious to try. Surprisingly, it's pretty good. Alright, let's see what else this will do. I'll try burning a penny, and, wow, it melted. How about a stack of pennies Yep, they're nothing but liquid metal now, and I'm thinking that slag in the mixture must be what's left of the copper coating. It's only taking about 4 seconds to melt these, and melting metal is really great, but now I want to see something burst. I wonder what would happen to this egg It's spewing some kind of debris and smoking like crazy. I hear.

Some little pops and it's even forming some interesting growths. huh, Look at that. But no explosion. How about if I put a pop top on this bottle of water and let the pressure build up Yeah, that's what I'm looking for. Let's do that again. The lid is back on, and pressure is building. Awesome! Alright, the sun is setting and I've readjusted my Aframe. I'm just wondering if this would ignite gasoline. It does. Hopefully it goes without saying that this is very dangerous and you shouldn't try this at home. Well, I'm convinced there's.

An insane amount of power behind these lenses. If you'd like to see where I got this one, take a look at my tutorial on how I hacked it out of an old TV. This one boiled water in less than a minute, welded a nickel to concrete, and instantly torched any piece of wood in it's way. Well that was fun, but I'm still hungry so I'll put everything away and go get some real home cooking. That's it for now. If you liked this project, perhaps you'll like some of my others.

How Solar Energy Is Converted To Electricity Through Solar Panels

Sunlight is made up of tiny packets of energy, called photons. Every minute, enough of this energy reaches the earth to meet the world's energy demand for a whole year. Photovoltaic panels consists of many solar cells, these are materials made like silicon, one of the most common elements on earth. The individual cell is designed with a positive and a negative layer to create an electric field, just like in the battery. As photons are absorb in the cell, their energy causes electrons to come free. The electrons move towards the bottom of the cell, and exit through the connecting wire. This flow of.
